On x86_64 the PTI entry trampolines are not in the kernel map created byperf tools. That results in the addresses having no symbols and preventsannotation. It also causes Intel PT to have decoding errors at thetrampoline addresses.

Workaround that by creating maps for the trampolines.

At present the kernel does not export information revealing where thetrampolines are. Until that happens, the addresses are hardcoded.
